CU/XLPE/CTS/PVC/SWA/PVC is a 3-core armored medium voltage cable that is available in 12/20kV to 18/30kV. Designed to excel in underground, industrial and highly corrosive environments, this electrical cable offers superior durability, electrical integrity and safety compliance. Its multi-layer CU/XLPE/SWA/PVC construction (copper conductor, XLPE insulation, copper tape shield, steel wire armor and PVC jacket) ensures resistance to mechanical stress, moisture and chemicals.

Product features

• CTS Copper Tape Shield: Eliminates partial discharges and improves voltage stability by 30% compared to conventional copper wire shielding.
• SWA Cable Steel Armor: Resistant to impact from excavators and rodents, suitable for direct burial (no additional conduit required).
• Double PVC sheath (ST2 class) with IEC 60811 salt spray test (1000h), suitable for coastal/chemical plants.
• Flame retardant rating: IEC 60332-3-24 (bundle burning class A), smoke density ≤ 60% (IEC 61034)
• Service life: XLPE insulation provides 40% longer service life compared to PVC cables in high temperature environments (e.g. steel mills).
